TCEQ can fine operators up to $25,000/day. Here's what's required, what gets cited, and how to close the gaps.
Stormwater compliance in Texas is administered by the Texas Commission on Environmental Quality (TCEQ) under the TPDES Multi-Sector General Permit TXR050000 (Texas Pollutant Discharge Elimination System). Commercial pressure washing operators must comply with permit conditions before discharging any wash water — including to sanitary sewer connections, where applicable. Operating without compliance documentation exposes contractors and property owners to per-day civil penalties.
Houston contractor cited solely for missing site inspection logs — no actual discharge required. $25,000/day penalty assessment. Economic benefit surcharge adds 50% to base penalty for violations where compliance costs were avoided.
In Texas, TCEQ specifically texas operates one of the most enforcement-active stormwater programs in the south. Across all MS4 enforcement programs, four documentation failures drive the majority of citations:
"Failure to comply with any permit requirement constitutes a violation. Civil penalties for violations may reach $25,000 per day per violation, accruing from the first day of noncompliance until the violation is corrected and documented." Texas Water Code §7.102; TCEQ Enforcement; +50% economic benefit surcharge per TWC §7.105 — TCEQ
Texas operates one of the most enforcement-active stormwater programs in the South. TCEQ's TPDES MSGP TXR050000 covers commercial pressure washing, and Houston and Dallas both operate Phase I MS4 programs with active mobile inspection capacity. A 50% economic benefit surcharge under Texas Water Code §7.105 means the effective maximum penalty is $37,500/day for violations where compliance costs were avoided — making the real exposure comparable to California and New York. A 2025 Houston case established that missing site inspection logs alone — without any documented discharge — triggers the full penalty. Chemical logs, pre/post photos, and SDS documentation are all required and regularly audited. San Antonio and Austin have adopted enhanced local MS4 ordinances with independent enforcement authority.
For pressure washing contractors, Texas's permit framework creates specific documentation obligations on every job: chemical log entries before work begins, containment setup verified with pre-job photos, wash water collected and disposed of at an approved facility or licensed sanitary connection, and post-job photos with GPS metadata and timestamp confirming the site was left without surface runoff. Each of these elements is independently verifiable by an inspector — missing any single item is sufficient for a notice of violation.
In Texas's largest markets — Houston, Dallas, and San Antonio — local MS4 permits add requirements on top of the state TCEQ baseline. Commercial pressure washing operators in these metros should verify local ordinance compliance with their municipal stormwater authority before beginning commercial operations. Municipal MS4 programs may require advance registration, bond documentation, or site-specific BMP plan approval beyond what TCEQ requires.
